3、MySecurityController
@Controller
public class MySecurityController {
private final String PREFIX = "pages/";
/**
* 歡迎頁
*
* @return
*/
@GetMapping("/")
public String index() {
return "welcome";
}
/**
* 登陸頁
*
* @return
*/
@GetMapping("/userlogin")
public String loginPage() {
return PREFIX + "login";
}
/**
* level1頁面映射
*
* @param path
* @return
*/
@GetMapping("/level1/{path}")
public String level1(@PathVariable("path") String path) {
return PREFIX + "level1/" + path;
}
/**
* level2頁面映射
*
* @param path
* @return
*/
@GetMapping("/level2/{path}")
public String level2(@PathVariable("path") String path) {
return PREFIX + "level2/" + path;
}
/**
* level3頁面映射
*
* @param path
* @return
*/
@GetMapping("/level3/{path}")
public String level3(@PathVariable("path") String path) {
return PREFIX + "level3/" + path;
}
}
4、自定義SpringSecurity的配置類(重點)
@EnableWebSecurity //開啓WebSecurity模式
public class MySecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
//super.configure(http);
//定製請求的授權規則
// 不同的角色可以訪問的權限不同
http.authorizeRequests().antMatchers("/").permitAll()
.antMatchers("/level1/**").hasRole("vip1")
.antMatchers("/level2/**").hasRole("vip2")
.antMatchers("/level3/**").hasRole("vip3");
//開啓自動配置的登陸功能，效果，如果沒有登陸，沒有權限就會來到登陸頁面
//1、/login來到登陸頁
//2、重定向到/login?error表示登陸失敗
//3、更多詳細規定
//4、默認post形式的 /login代表處理登陸
//5、一但定製loginPage；那麼 loginPage的post請求 /userlogin就代表處理登陸
http.formLogin().usernameParameter("user").passwordParameter("pwd")
.loginPage("/userlogin");
//開啓自動配置的註銷功能。
//1、訪問 /logout 表示用戶註銷，清空session
//2、註銷成功會返回 /login?logout 頁面；
http.logout().logoutSuccessUrl("/");//設置註銷成功以後來到首頁
//開啓記住我功能
//登陸成功以後，將cookie發給瀏覽器保存，以後訪問頁面帶上這個cookie，只要通過檢查就可以免登錄
//點擊註銷會刪除cookie
http.rememberMe().rememberMeParameter("remeber");
}
//定義認證規則
// 需要對密碼進行加密 PasswordEncoder
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
// 這些數據正常應該從數據庫中讀
// 給不同的用戶設置不同的角色
auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
.withUser("zhangsan").password(new BCryptPasswordEncoder().encode("123")).roles("vip2", "vip3")
.and()
.withUser("lisi").password(new BCryptPasswordEncoder().encode("123")).roles("vip1")
.and()
.withUser("zy").password(new BCryptPasswordEncoder().encode("123")).roles("vip1", "vip2", "vip3");
}
}
